Question? What is the difference between the different Si-Quat products that use the primary Active Ingredient 3-(trimethoxysilyl) propyldimethyloctadecyl ammonium?
Answer: The Silane Quaternary Ammonium Chloride Compound 3-(trimethoxysilyl) propyldimethyloctadecyl ammonium chloride, aka ‘Si-Quat’, was invented in the 1970s by DOW CORNING Chemical Company. The compound has been in use for over 40 years and has been proven to be safe and effective against a wide variety of microorganisms. Its unique structure allows the molecule to attach to almost any non-porous surface and fabrics and other types of textiles.
The Si-Quat molecule is licensed to manufacturers around the world and is commonly private labeled by dozens of companies. The chemistry of the products using the 3-(trimethoxysilyl) propyldimethyloctadecyl ammonium chloride compound, aka Si-Quat, is the same or very similar. The main variance in the active ingredient is typically the concentration level.
Below is a comparison chart of four popular Si-Quat products.
